Bug 413423

Application: systemsettings5 (5.17.1)

Qt Version: 5.13.1
Frameworks Version: 5.63.0
Operating System: Linux 4.12.14-lp151.28.20-default x86_64
Distribution: "openSUSE Leap 15.1"

-- Information about the crash:
- What I was doing when the application crashed:

I went to the compositor settings to re-enable it. After setting the checkbox to off and on again I clicked Apply button, then closed the app using the window close button. A message about app crash appeared.

The crash can be reproduced sometimes.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
